If you’ve ever received immigration paperwork, you may have noticed a unique ID called an Alien Registration Number (A-Number).
What It Is
- A 7–9 digit number assigned by USCIS to most immigrants.
Appears on green cards, EADs, and immigration notices.
Why It Matters
- Used to track your immigration history.
Needed for case inquiries, forms, and FOIA requests.
Quick Tip: Keep your A-Number safe and consistent across all filings.
At Global Immigration Partners, we help clients use their A-Number correctly to avoid delays or mismatches in the system.
